PENI-IOLDER.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed September 7, 1912. Serial No. 719,055.

To all whom it may concern:

Be it known that I, HENRY J. ROTH, a citizen of the United States,residing in the borough or Brooklyn, county of Kings, city and State ofNew York, have invented certain new and useful Improvements inPenholders, of which the following is a specification.

This invention is directed to the provision of an improved form ofpenholder of the type in which a grip is provided at the end of theholder so constructed that it can be. moved inwardly a small amounttoward the axis of the holder in response to the pressure of the fingersthereon. Penholders of this character can be more readily held in thehand in the desired position and can be used with less of a tiringeffect upon the hand.

In accordance with the invention, a sleeve or tube is provided upon theend of the holder made of such material as cork which will depress ormove inwardly when subjected to pressure by the fingers, and theconstruction is such that an air space is provided within this sleevebetween the ends thereof where the sleeve is supported. In this way, thedesirable capacity for depressing in response to pressure is obtained inthe grip and the structure may be such that the holders may bemanufactured at comparatively low cost. This low cost is due primarilyto the fact that the sleeve or tube of cork or similar material may beof uniform cross-sectional shape throughout, the supports for the tubebeing of greater diameter at the ends of the sleeve than between thoseends where the air space is provided within the sleeve.

The preferred embodiment of the invention is illustrated in theaccompanying drawings in which Figure l is an elevation of the pen andholder, Fig. 2 is a longitudinal section of the end of the holder, Fig.3 is a similar view showing certain of the parts in elevation, and Fig.4 is a transverse section on line 44: of Fig. 2.

Referring to these drawings, 5 indicates the shaft of the holder,preferablyround and tapering toward one end. At its larger end, it isreduced in size to form a tenon consisting of two cylindrical portions 6and 7 the portion 7 at the end being of smaller diameter than theportion 6. This provides a shoulder 8 at the junction of the twoportions 6 and 7 and a shoulder 9 at the junction of the portion 6 andthe shaft 5. A tube of thin sheet-metal 10 is mounted on the portion 7that is, the portion 7 projects into one end of tube 10 with the end ofthe tube abutting against shoulder 8. This tube is of less exteriordiameter than the diameter of the cylindrical portion 6. The oppositeend of tube 10 receives the usual split metallic thimble 11 for holdingthe pen between it and tube 10.

On the outer end of tube 10 is a circumferential enlargement 12 of thesame exterior diameter as" the portion 6 of the tenon on the shaft 5.Preferably, this enlargement 12 is a small metallic tube or ring drawninwardly at one end so as to bear on tube 10. The other end of the ring12 bears against a metallic ring or washer 13 which fits snugly on tube10 as shown and is preferably positioned by spreading the extreme end oftube 10 as indicated.

The grip of the holder is shown at 14. It is in the form of a tube orsleeve of uniform cross-section throughout and is made of cork or asimilar material which will give when subjected to pressure. At one end,this sleeve fits upon and is supported by the portion 6 of the shaft,its end abutting against the shoulder 9. Its opposite end fits upon andis supported by the enlargement or ring 12, the extreme end abuttingagainst washer 13. As both the ring 12 and the cylindrical portion 6 areof larger diameter than the exterior diameter of tube 10, a space isprovided between sleeve 14 and tube 10 between the ends of the sleeve,as is shown in Figs. 2, 3 and 4. By reason of the provision of this airspace within the grip, the sleeve 14 will give and be depressed when theholder is gripped in the hand, the walls of the sleeve moving more orless into the inclosed space within it, dependent upon the pressure. Bythis construction, the holder is made much more convenient to use, muchmore so than when the material constituting the grip lies directlyagainst the shaft or a part mounted thereon. Furthermore, thisconstruction permits of manufacturing the holders at low cost. It willbe noted that the tube or sleeve 14 of cork is of uniform cross-sectionfrom end to end. This form of sleeve may be used because of theprovision of supporting surfaces coacting With the ends of the sleevewhich surfaces are of larger diameter than the portion of the structurelying between them.

If desired, a metallic ferrule 15 may be provided at the upper end ofsleeve 14. This ferrule is a thin metal tube and is inserted in the endof sleeve 14 before assembling the latter on the holder so that theflange at its end will abut against shoulder 9.

Having described my invention, What I claim as new therein and desire tosecure by Letters Patent of the United States is:

A penholder comprising a shaft reduced in size at one end thereof toprovide two shoulders and cylindrical portions of different diameters,adjacent thereto a tube of thin sheet-metal of less exterior diameterthan the larger of said cylindrical portions and into one end of Whichthe smaller of said portions projects to support the tube on the shaft,a pen-holding clip at the opposite end of said tube, a circumferentialenlargement on said tube adjacent to said opposite end and a tubulargrip of cylindrical form presenting an unbroken cylindrical surface andof substantially uniform cross-section throughout, said gri 3 inclosingsaid tube and mounted at one en upon the larger of said cylindricalportions abutting the shoulder at the end thereof and at the other endupon said circumferential enlargement, said grip being spaced apart fromsaid tube and being made of such material that it may be depressed moreor less into the space between it and the tube, substantially as setforth.
